I took the LEAF in today to Nissan of Fife (WA), asking the dealer to inspect the brakes and look at the lack of regeneration. Their reply:

Verified Cust Concern. Found HV Battery is not able to accept regen charging anymore. Needs new battery ... is too weak to accept regen charging. Needs new and improved battery. Cost to replace battery - $6,294.65 plus tax.

As for the brakes - 5mm on front and 6mm on rear. The advisor went on to say that I should expect they will wear out faster now that the regeneration has gone away.

LEAF has ceramic brake pads so they will still last a while. Since ceramic pads cause more wear on the rotors, the rotors will likely need replacement when the pads are worn out so you might as well use the original brakes as long as you can (then replace pads and rotors).

The crazy thing is (and there's a whole thread about this already), if you can charge the car, the car can take at least some regenerative braking. On a '11, you'd think that would be a minimum of 3 kW of regen. With LeafSpy or LeafDD, one can easily see that the car severely limits the amount of regenerative braking depending on vehicle speed and SOC by looking at regen power and battery pack voltage. The battery can take regenerative braking, but it's programmed not to and the limits get more and more conservative as the battery loses capacity.

Duh!

My thoughts exactly on the brakes. I was trying to link the lack of regeneration to the grab and release braking I experience at LBW or VLB with light brake application (exiting from freeway or approaching a light). My simple interpretation is the system wants to put the energy to the battery but it can't and the brakes have to release - it can be quite a jerking motion in this situation as I come to a light.

The advisor told me the reading they were getting off my car was 6 and the normal range is 20 to 25. What the units are I don't know. That's all I can add to the request for an update on my brakes and regen. Steve

+$6499 battery
-$1000 core
+$225 retrofit kit
------------------------
$5724 total for parts at full MSRP
+$570.65 labor???

Looks like they are charging you full MSRP price on the battery (you can find the battery for over $1000 below list price at other dealers- a good comparison is Courtesy Nissan at CourtesyParts.com). Also, Nissan's own labor estimates for a battery swap is 3 hours. So they are charging $190.22 for labor too, which is high, or they overestimated the labor time.

Is there sales tax on a replacement battery? That's 9% - 10% in California.

Yes, that's an added expense. If you live north enough, you can always find a dealership in Oregon to avoid the tax. :)

That is pretty incredible ! 150k miles and the brake pads are still good to go :) Imagine if the regen had never given up? The pad would be in even better shape! I just wish Nissan could do a replacement on the battery for half that cost :(. I guess that they did not check on the rotors? Someone mentioned they could be a little more worn due to the ceramic break pads. So I guess when someone said the rotors wouldn't last as much as the pads might be correct after all.

What is the main wear for rotors? I read http://www.intuneautos.com/brake-rotors ... me-warped/ and it sounds to me like it would be braking. Though it also mentions heat? But really I'd say what would cause the most heat is when you apply the brakes? Regular heat from the atmosphere can't possibly cause damage to the rotors... can it? It also mentions dirt and other debris.... would rust be another factor? But if it were rust it would be more if you live in a moist area? Very humid? Would it be safe to say if you didn't ever need to use the regular breaks that the rotors could almost last indefinitely???

I still wish Nissan would have done something for Mr. Taylor. Even a discount on a battery replacement would have been great (Down to less than 50% cost would be good). Thoughts?

Thank you so much for the update! From what I read here if the battery can still intake regular charging from an outlet it should still allow regenerative breaking....

Congrats Steve on making 150k, bummer your car can't make the commute anymore. I too have a substantial commute and use my LEAF to save money. My commute is 44 miles each way, I am actually the Mechanical Designer for a company that makes level 2 EVSE. I purchased a 2014 LEAF on Memorial Day weekend in 2014. My car just turned 63K yesterday (26 mo). We have level 2 charging station at work and have additional level two station at home. I haven't lost a bar yet, but estimate I'm down 12%, though I lost range after purchasing none eco tires. The Ecopia tires wear right off it, drove them to bald and only got 37k. I was fortunate to take advantage of the Georgia EV tax credit of $5k before they eliminated it in 2015. I actually leased two of them so have $10k credit over 5 years. I just turned in the 2015 LEAF with 24K after 2 year a my wife lost her job so I wanted to drop the payment. My goal will be to reach 150K also. I do not use DC quick, only 2 times in the two plus years. My driving patterns have worked out that I can put 600 mi/wk on without quick charging. I level 2 charge 3x/day, once at work, immediately when I get home for 30 minutes and then overnight after all the driving of my kids to work and sporting practices. Haven't spend a dime on maintenance on the car and hope it continues. I hope the 2014 battery holds up a little longer than your 2011.

Bummer, day I post full bars, I dropped one on way home from work 63060.
